Jon,
I`ve also searched and have not found a Volvo rotor that will work.
Therefore, I`m ASSUMING the Volvo cap has the spring loaded contact, since the Volvo rotor has the flat contact in the center.
ALSO, that means the earlier M3 rotor, Bosch #1-234-332-391 SHOULD work. This is the cheaper M3 rotor, $19.28 from www.thepartsbin.com. Also, the Volvo cap, Bosch #1-235-522-382 is $29.22 from The Parts Bin.
I`m going to order both parts to see if they are compatable. I`ll keep you posted.
John

It appears that all the 740s use the same caps and rotors, whether they are 8V or 16V, Turbo or not.

They look like this:

Now, that cap looks very familiar but the rotor looks a little different. Here's a picture of what they say an M3 rotor should look like. This also matches the ETK diagram:

So, I recall people talking about spring-loaded this, and gapped that. What I want to know is: are these rotors compatible? It looks like they mount in completely different ways. If not, I cannot, for the life of me, find any Volvo rotors that look remotely similar to the BMW one above.

I do notice that they always list another PN for M3 rotors but nobody has a picture of that one.

So, can anyone straighten this out for me?

Thanks,
Jon
